WINDOW-SHADE FIXTURE.

SPECIFICATION forming part of Letters Patent No. 642,468, dated January30, 1900.

Application filed November 2, 1899. Serial No. 735,625. (No model.)

To all whom t may concern:

Be it known that I, MATTHEW A. MARR, of the city ot New York, borough ofManhattan, in the county and State of New York, have invented a new andImproved l/Vindow- Shade Fixture, of which the following is a full,clear, and exact description.

This invention relates to improvements in Window-shade lixtures of theclass in which the roller carrying the shade kis-adapted to be moved upand down with relation to the Window-casing, so that light may beadmitted over the top while the shade closes over or partly over thelower portion of the window; and the object of the invention is toprovide a fixture the brackets and guide-rails of which are soconstructed that there can be no lateral play of the brackets or anydisplacement of their axial relation to each other, thus insuring aneasy and even adjustment of the shade-roller.

A further object is to provide a simple means for preventing anaccidental displacement of'the roller from its brackets; and a stillfurther object is to provide the roller with a longitudinalspring-yielding bearing to permit of its automatic adjustment topossible varying widths betweenthe side rails of a window-casing.

I will describe a window-shade fixture embodying my invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is an elevation showing a fixture embodying my inventionapplied to a windowcasing. Fig. 2 is a section on the line 2 2 ofFig. 1. Fig. 3 is a section showing a means for permitting longitudinaladjustments of the roller. Fig. 4 is a side view of one of the brackets,and Fig. 5 is a cross-section of a guide-rail made of sheet metal.

Referring to the drawings, 1 designates a roller of the usual springform and to which the shade 2 is attached. A block 3, extended throughone end of the roller and having connection with the spring in theroller, is seated in a bracket 4t and is held from accidentaldisplacement from the bracket by means of a set-screw 5, engaging in atapped hole in the bracket and impinging against the block. This screwalso holds the block from longitudinal movement in the bracket. At theopposite end a bearing-pin 6 is designed to rotate in a bracket '7, andon the outer end this pin has a head 3 to prevent its movement inwardrelatively to the bracket. The bearing-pin 6 hasaspring-yieldinglongitudinal movement relatively to the roller 1. As hereshown, a spring 9 surrounds the bearing-pin within the roller, the saidspring bearing at its outer end against a plate 10, secured to the endof the roller and through which the bearing-pin is movable, and at theother end the said spring bears against a pin 11, passed through thebearing-pin. A pin 12 is passed through the roller 1 and through alongitudinal slot 13 in the bearingpin. This construction will permitthe bearing-pin to move longitudinally, but will cause it to rotate withthe shade-roller. The object of the spring-yielding bearing-pin is topermit of longitudinal adjustment to accommodate the fixture to possiblevarying distances be-V tween the side rails of a window-sash from itstop to its bottom, as sometimes occurs by the settlin g of a building.

The brackets 4 and 7 are substantially of similar construction and maybe of cast metal or stamped. Each one has an inwardly-extended arm 14 atits upper end and an inwardly-extended arm'15 at its lower end, thesearms being respectively above and below the parts in which the block 3and bearing 6 engage, so that the brackets will be prevented fromtilting forward under the weight of the shade. The arms 14 and 15 havevertical substantially V-shaped openings in which correspondingly-shapedguide-rails 16 engage, these guide-rails being secured to the oppositeside rails of the window-sash. The guiderails have their inner surfaces17 made lat and bearing closely against the flat wall of the openingsthrough the arms 14 and 15, and as the rear and front walls of theseopenings engage with the web portion of the rails it is obvious thatthere can be no lateral play of the brackets relatively to the rails, asoccurs when round or substantially round guiderails are employed. Therails may be made IOO of solid metal, as indicated in Fig. 2, or theymay be made of sheet metal bent into form, as indicated at 18 in Fig. 5.

From the bracket 7 a cord 19 passes overa roller 20, arranged in theupper portion of the Window-sash at one side', thence overa pulley 21 atthe other side, and then down to a connection with a clip 22, and fromthe bracket 4 a 'cord 23 extends over the pulley 2l, and thence throughopenings in the clip 22, which secures the cords together in such mannerthat they will pull evenly upon drawing downward on the cord 23.Obviously by drawing up on the cord 23 the roller carrying the shadewill be moved upward, and by loosening the strain on the cord theWeigh-t of the shade and its roller will move the shade downward. Whenthe shade and its roller are properly adjusted as to height, the cord 23is att-ached to a suitable cleat 2l on the window-casing.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a window-shade fixture, a roller, guiderails,brackets mounted to slide on the guiderails, a pin having longitudinalspring-yielding connection with the roller at one end, and a head on thepin adapted to engage the outer side of one of said brackets, thetendency of the spring being to draw the pin inward, substantially asspecified.

2. In a Window-shade fixture, guide-rails, brackets mounted to slide onsaid guide-rails, a roller, a bearing-pin extended from said roller, apin extended through the roller and through a longitudinal slot formedin the inner end of the bearing-pin, a spring arranged Within theroller, and surrounding the bearing-pin, said spring having a tendencyto cause an inward movement of the bearing-pin,

and a head on the outer end of said pin for engaging with theoutersurface of the bracket in which the pin is supported, substantiallyas specified.
